1995 SUBARU LEGACY wheel alignment

Symptom and possible cause Remedy
5. Noises when cornering


1Damaged differential gear. Replace.


2Excessive wear or damage of thrust washer. Replace.


3Broken pinion mate shaft. Replace.


4Seized or damaged side bearing. Replace.
6. Gear noises
Since noises from engine, muffler, transmission, propeller shaft, wheel bearings, tires, and body are sometimes mistaken for noises
from differential assembly, be careful in checking them. Inspection methods to locate noises include coasting, accelerating, cruising,
and jacking-up all four wheels. Perform these inspections according to condition of trouble. When listening to noises, shift gears into
four wheel drive and fourth speed position, trying to pick up only differential noise.


1Improper tooth contact of hypoid gear. Readjust or replace hypoid gear set.


2Improper backlash for hypoid gear. Readjust.


3Scored or chipped teeth of hypoid gear. Replace hypoid gear set.


4Seized hypoid gear. Replace hypoid gear set.


5Improper preload for front or rear bearings. Readjust.


6Seized, scored, or chipped front or rear bearing. Replace.


7Seized, scored, or chipped side bearing. Replace.


8Vibrating differential carrier. Replace.
2. Propeller Shaft
Symptom and possible cause Remedy
1. Vibration of propeller shaft
Vibration is caused by propeller shaft during operation and is transferred to vehicle body. Generally vibration increase in proportion to
vehicle speed.


1Worn or damaged universal joint. Replace.


2Unbalanced propeller shaft due to bend or dent. Replace.


3Loose installation of propeller shaft. Retighten.


4Worn or damaged center bearing and damaged center mount-
ing rubber.Replace.
2. Tapping when starting and noise while cruising, caused by propeller shaft.


1Worn or damaged universal joint. Replace.


2Worn spline of sleeve yoke. Replace.


3Loose installation of propeller shaft. Retighten.


4Loose installation of joint. Replace.


5Worn or damaged center bearing and damaged center mount-
ing rubber.Replace.
NOTE:
Vibration while cruising may be caused by an unbalanced
tire, improper tire inflation pressure, improper wheel
alignment, etc.

If toe-in or front camber tolerance exceeds specifications,
adjust toe-in and camber to the specification.

The other items indicated in the specification table can-
not be adjusted. If the other items exceeds specifications,
check suspension parts and joint portions of body suspen-
sion parts for deformities; and replace with new ones as
required.
